Procedure
A slurry of 177.0 g (1.0 mole) of 4,5-dichloro-o-phenylenediamine in 750 ml. ethanol was added to a warm near solution of 313.1 g (2.0 mole) of 5-chlorosalicylaldehyde in 2250 ml. of ethanol with mechanical stirring in a 5000 ml, 3-neck flask. A brown solution formed, and a light brown solid began to precipitate after 10-15 minutes. Stirring at room temperature was continued for six days. Thin-layer chromatography indicated that the reaction was substantially complete at the end of six days.
